Should net neutrality rules stop T-Mobile's music streaming offer?

[Commentary] When T-Mobile announced that it would exempt streaming music services from its wireless data caps, I thought it was the best reason yet for Washington to stop the company from being swallowed up by Sprint. But some consumer advocates thought it was a good reason for Washington to spank T-Mobile.

With Sprint and T-Mobile trailing Verizon and AT&T, we've had two companies trotting out innovative offers in a bid to attract customers. The two companies' track record of experimentation argues against the merger, particularly in respect to the Federal Communications Commission's public interest test. After all, two innovative underdogs are invariably better than one if both can survive in a market. That's a big if, however, and it's likely to be the key question reverberating around any Sprint attempt to buy its smaller rival.
